Bud, Not Buddy

Bud hit Todd because he called him Buddy. He'd already corrected him verbally twice..... on top of which, Todd stuck a pencil up his nose. Enough was enough.

Todd laughed. "I've never gotten it in as deep as the N on any of you other little street urchins. I just might enjoy your stay here. Who knows what other things you could be number one in, Buddy?"
I'd already told him twice that my name was Bud, not Buddy.
I didn't care that Todd Amos was twelve years old, I didn't care that he was twice as big as me, and I didn't care that his mother was being paid to take care
of me. I wasn't about to let anybody call me Buddy and stick a pencil up my nose all the way to the R.
I swung as hard as I could at Todd's big balloon head. Somewhere between the time I threw my punch and the time it landed my fist came open and when my hand landed it made a pop like a .22 rifle going off. Todd fell on the floor like he'd been coldcocked.
